The following table illustrates the signals, inputs and outputs of the module:
Pos.
Name
Description
A
-
Power status LED, green. The possible states are:
• Off: power supply absent.
• On fixed: power supply and communication with the release
present (with a release with the Alive LED option disabled).
• On, with one flash per second (synchronized with that of the
green LED on the release): power supply and communication
with release present (with a release with the Alive LED option
enabled).
• On, with two quick flashes per second (not synchronized
with those of the green LED on the release): power supply
present, and communication with release absent (for example,
because Local Bus disabled)

.
B
I x1
(2)
LED for signalling the physical state of the input H x1, green.
The possible states are:
• Off: floating input.
• On fixed: input short-circuited on H Cx.
C
I x2
(2)
LED for signalling the physical state of the input H x2, green.
The possible states are:
• Off: floating input.
• On fixed: input short-circuited on H Cx.
D
O x1
(2)
LED for signalling contact K x1 - K x2, green. The possible
states are:
• Off: contact open.
• On fixed: contact closed.
E
O x2
(2)
LED for signalling the state of the contact K x3 - K x4, green.
The possible states are:
• Off: contact open.
• On fixed: contact closed.
F
H x1
(2)
Input I x1.
G
H Cx
(2)
Conductive part of the inputs H x1 and H x2.
H
H x2
(2)
Input I x1.
I
K x1, K x2
(2)
Output contact pin O x1.
L
K x3, K x4
(2)
Output contact pin O x2.
(1)
The absence of communication is signalled immediately by the power LED, unlike the outputs which
(apart from those programmed to be activated in the case of disconnection) are deactivated if the condition
persists for at least 8 s.
(2)
With x = 1, 2, or 3.
